Maryland State Police troopers are investigating a collision involving a school bus Wednesday morning in White Plains.

At 9:51 a.m. Aug. 28, troopers from the La Plata barrack responded to an accident at the intersection of U.S. 301 and Billingsley Road. Troopers arrived on the scene at approximately 9:55 a.m.

Preliminary investigation revealed that a flatbed tow truck driven by Dwain Evan Blankenship, 46, of Hughesville was slowing to a stop for a solid red arrow in the left-turn lane traveling from southbound U.S. 301 onto Billingsley Road.

The school bus transporting 20 eighth-graders from the Calverton School, a private school in Huntingtown, was traveling south on 301. The operator of the school bus, Derek Ingram, 57, of Lusby, was unable to stop before hitting the back of the tow truck, police reported.

As a result of the collision, injuries were sustained by three people on the bus — Jennifer McAneny, 44, of Chesapeake Beach and two students. They were taken to University of Maryland Charles Regional Medical Center in La Plata by ambulance for treatment. All three had injuries that were not life-threatening, police said.

Spencer Taintor, head of the Calverton School, said that McAneny, a teacher at the school, was released from the hospital shortly after arriving and the two students remained at the hospital during the day as a precaution. They had minor aches, he said. The remaining students were put on another bus and taken back to school.

Taintor said the eighth-graders were going to Colonial Williamsburg for a field trip.

The trip was postponed 24 hours in order to re-evaluate and err on the side of safety, he said.

Troopers from the commercial vehicle enforcement division investigated the damage to both commercial vehicles. Damage sustained from the collision covered the right front bumper and corner of the school bus and the left rear corner and bed area of the tow truck.

Results of that investigation have not been finalized.

On Thursday morning, school officials said both students who were sent to the hospital were released Wednesday and did not sustain major injuries. All 20 students continued their field trip Thursday.

The investigation is continuing. Anyone who saw the accident is asked to call trooper J. Harrod at 301-392-1200.
